Neal Fowler
Analyst · Wedbush. Your line is open
Good morning, everyone, and thank you for joining us. On the call with me today are Rich Katz, our Chief Financial Officer; and Dr. Robert Roscigno, Senior Vice President of Product Development and Program lead for LIQ861. This morning I will summarize our recent accomplishments and provide an update on our two pipeline programs, LIQ861 and LIQ865. Rich will provide a brief summary of our financial results for the third quarter of 2019. And then, I will wrap up with an update on our upcoming key milestones. After our prepared remarks, we will open the call for your questions. Important highlights include, we completed the registrational studies of 861 to support our NDA submission, including the comparable PK program. We initiated clinical studies to evaluate long-term safety, tolerability and hemodynamic effects of 861. We are engaged in pre-NDA meetings with FDA in preparation for the NDA submission targeted for the first quarter of 2020 and we continue the tox studies for 865 with the goal of supporting a Phase 2 clinical program. With those highlights in mind, I'd like to provide some additional details on our activity in the last quarter, starting with our lead program 861. As a reminder, 861 is an inhaled dry powder formulation of treprostinil, a prostacyclin analog used to treat PAH by targeting the pulmonary arteries. It combines the demonstrated benefits of inhaled prostacyclin therapy with fewer systemic toxicities than oral or infused options. We believe that 861 has the potential to maximize the therapeutic benefits of treprostinil by safely delivering higher doses directly into the lungs using a convenient palm sized disposable dry power inhaler. To date we have generated a robust set of information on the safety, tolerability and clinical benefit that 861 may provide PAH patients transitioning from Tyvaso or those naive to prostacyclin therapy. As we evaluate the totality of the data collected, I wanted to point out a few highlights from the program today. Final enrolment in the pivotal INSPIRE trial to assess safety and tolerability through month two included 121 PAH patients in two groups. 55 patients transition from a stable dose of Tyvaso or transition patients and 66 patients who are prostacyclin naive and stable on less than two approved oral PAH therapies known as add on patients. Consistent with preliminary data presented in the second quarter of 2019, 861 was observed to be well tolerated. Treatment emergent adverse events were mostly mild to moderate in nature, even at the highest dose studied, the 150-microgram capsule strength of 861. Most patients remained on treatment throughout the study with 96% of transition patients, and 91% of add on patients receiving treatment to month two. More than 80% of add on patients titrated to the 75 microgram capsule strength of 861 or higher within the first two months of treatment. More than 90% of all patients who completed two months of treatment maintained or improved their New York Heart Association Functional Class. And lastly, both patient groups saw improvement and exploratory measures of six-minute walk distance and quality of life as measured by the Minnesota Living with Heart Failure Questionnaire. So, the primary endpoint of INSPIRE was at the month two time point, we continue to treat patients who chose to remain on LIQ861. We were pleased to see that more than 80% of INSPIRE patients remained on study drug and month four with no significant changes in safety or tolerability compared to month two. In addition to completing the INSPIRE study, we were also pleased to complete a second supplemental PK study. The results further confirmed the comparative bioavailability of the 75 microgram capsule strength of 861 to 54 micrograms or nine breaths of Tyvaso, the reference list of drugs. We expect to present the clinical data from INSPIRE, and the PK studies in greater detail at medical conferences and in publications during the course of 2020. With the INSPIRE study closed, we are actively managing two clinical trials with 861. First, we have transitioned INSPIRE patients who wish to continue 861 treatment into an open label extension study, which we plan to continue until potential FDA approval. And secondly, we are also enrolling patients in a clinical study in Europe to characterize the hemodynamic dose response relationship to 861. The company is now preparing to submit the NDA for 861. To that end, we have actively engaged the FDA in pre-NDA meetings. During the third quarter, we hosted the FDA at our site as part of their emerging technologies program. Their visit help facilitate the pre-NDA CMC meeting a month later, where we confirm no new CMC requirements for an NDA submission. Our pre-NDA meeting to discuss clinical and non-clinical matters of the NDA will be conducted later in the fourth quarter. Pending a successful meeting we continue to target an NDA submission in the first quarter of 2020. With regard to LIQ865, significant progress has been made with our lead program, as I mentioned before, and we continue to advance our second program 865, which is a print formulation of bupivacaine to treat local postoperative pain for three to five days with single administration. In preparation for Phase 2 studies we’re conducting a toxicology program to assess 865 in multiple non-clinical tissue models. In one study to assess incision tensile strength after healing results were acceptable and not statistically significant from controls. In a second study to assess bone fracture healing we observed dose dependent delayed healing at the two 865 doses studied. However, there were no adverse effects noted on the surrounding soft tissues. We’re planning to study lower doses of 865 to determinate a no adverse effect level on bone healing. And lastly, we expect results from an additional soft tissue toxicology study later in the fourth quarter. Results from all of the toxicology studies will be reviewed and if supportive, we intend to initiate Phase 2 program in 2020. I would like to turn the call over now to Rich to review our third quarter financial summary.
